CDC can't study gun violence because they are out to ban guns. Quote from the CDC head Mark Rosenberg from 1994: “We need to revolutionize the way we look at guns, like we did with cigarettes. Now it [sic] is dirty, deadly and banned.” This isn't an okay attitude for a government employee to have because the bill of rights guarantees all Americans the right to bear arms.
I was born and raised in a midwest state that relies largely on tourism. The pheasant hunting season in particular is a big deal. My family, friends, and just about everybody I knew owned guns. In that context, I knew absolutely nobody who ever used a gun to hurt a human being. And I knew all these people for several decades.
Blaming the guns is just wrong. There are other factors at play here. We need to leave the framework (2nd amendment) alone and start working the root cause issues.
